NZXT's new Kraken X61 has a new trick up its sleeving, a variable speed pump for those who want as quiet a cooler as possible. [H]ard|OCP found that the design was so efficient and quiet that they really didn't need that feature but for those with sensitive ears it might be a perfect solution.  The performance was on par with many of the other AIO coolers they have tested however the price was higher at ~$140 which may be a deal breaker for some.  The other possible barrier for potential purchasers is the lack of documentation for both the physical installation and the software; experienced users will not be daunted by this but those who are not comfortable with muddling around in advanced settings and mounting coolers may want to print out the online docs before attempting to use the X61.

"NZXT is known to many enthusiasts for its computer cases but not so much for its Kraken series of CPU closed loop liquid coolers. After a year of design NZXT has introduced its new Kraken X61. Its claim to fame is that it is the "world's first variable speed liquid cooler." Let's see what this variable RPM pump does for the new Kraken."
